better companies will tell you that you can power their subs with pretty much any power you want to as long as you can set gains and adjust as needs to be. I have heard of many people running subs off 50 watts and being happy. I have heard many people pushing 1000 watt subs with "1800 watts", but the 1800 is toned down to where it is only realistically pushing about 1000 or whatever the speaker is handling well. It all depends on your knowledge what you can do with a speaker.
